MANY, ASSIGNOBS TO I. G. EA BBENINDUSTBIE AKTIENGESELLSCHLFT, OF FRANK-FOBT-ON-TEE-MAIN, GERMANY, A CORPORATION OF GERMANY rnonucrrou oroxma'rron PRODUCTS FROM CRUDE PABAFFIN E YDBOCABBO NS,

'WAZES, AND THE LIKE' lom'awing. Application filed April 8,

- such as air,'it is diificult to obtain oxidation oxygen, such as air,mixed with nitric oxides,

is emplo' ed in a crude' or in a partially purified con ition, as forexample in the form of crude parafiin scale, because the impuritiescontained in the crude paraflin wax ver considerably retard the actionof the oxi izing agent.

We have now found that crude paraffin wax,

urified paraiin wax, and thelike are directy and quicklyconverted intoyaluable oxidation products by passing gases containing products wheninitial material through the liquefied crude. parafiin wax. Theoperation may be performed in various ways, as for example, in vesselsprovided with inert or active fillers of large superficial area whichprocess can be performed also in a cycle. The oxidizing action ma beaccelerated by the employment of suita le such as calcium or aluminiumoxide or compounds of man anese. The temperature employed should e ofthe araflin wax, that is above about 45 to and not higher than about160C.

The following examples will further illustrate the nature of the saidinvention which however is not limited thereto.

Enample 1 Brown paraifin scalesare heated to 150 C. v

which term is meant to include partially I catalysts,"

above the melting point 1029, Serial no. 353,678, and in Germany April25, um.

242, and still'contains 15 per cent by weight of unsaponifiableconstituents.

The gaseous mixture obtained in the oxidation of ammonia can beadvantageously employed as the mixture containing ides, being usedeither by itsel with oxygen.

or mixed Ewample 2 Crude scales of paraffin wax together with 0.1 percent by weight of barium acetylacetonate g L cm-c=cn-oo.on.

are treated at 150 C. with a current of air- Example 3.

Crude paraflin wax with a content of 95 per cent of. parafiin is'mixedwith 0.2 per cent by weight of manganese acetylacetonate and treated atfrom,14. 0 to 145 C. with a current of aircontainingOJ per cent byvolume of nitrogen oxides in the manner described in Example 1. Afterblowing for 6 hours a product showing an acid value of 177 and asaponification value of 219 is obnitric ox-' tained which contains 44per cent by weightof unsaponifiable matter.

What we claim is The process for the reduction or oxida- 5 tion productsfrom crude paraflin hydrocarbons and waxes, which comprises actin uponthe said initial materials in the. liquig state with gases containingoxygen and nitric oxides in the presence of filler. bodies with a 0large superficial area and of a metal enolate'. In testimony whereof wehave hereunto set our hands. 7
